Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of this utility model protection.
This utility model provides a kind of safety and a kind of surgical operating instrument with above-mentioned safety of surgical operating instrument, be described for ease of the work process to safety and operation principle, in the process of in the present embodiment, safety being described, introduce the related notion to surgical operating instrument, therefore, in literary composition, no longer separately the operation principle of the surgical operating instrument with above-mentioned safety is described.
Incorporated by reference to Fig. 1 with reference to figure 2, Fig. 3 and Fig. 4, wherein, a kind of structural representation of the surgical operating instrument safety that Fig. 1 provides for this utility model embodiment; The structural representation of discharge cock in the time of off-position in the safety of the surgical operating instrument that Fig. 2 provides for this utility model embodiment; Structural representation when discharge cock is not pulled the trigger in opening position and firing handle in the safety of the surgical operating instrument that Fig. 3 provides for this utility model embodiment; Structural representation while reset after firing handle percussion in the surgical operating instrument that Fig. 4 provides for this utility model embodiment.
As shown in Fig. 2 Fig. 3 and Fig. 4, in a kind of specific embodiment, the surgical operating instrument that this utility model embodiment provides comprises handle body 3, be installed in the firing handle 5 of handle body 3, be installed on handle body 3, for regulating the drive rod 4 of end effector opening and closing state, the end effector being in transmission connection with drive rod 4, and be installed on the safety in handle body 3, wherein, the discharge cock 1 of these safety locks firing handle 5 in the time of off-position, prevent that firing handle 5 from carrying out firing action, discharge cock 1 is in the time opening, firing handle 5 can be carried out firing action, and when firing handle 5 carries out resetting after firing action, discharge cock 1 automatically resets to off-position, again firing handle 5 is locked, can prevent the accident that firing handle 5 is carried out secondary percussion, safety while improving surgical operating instrument operation.
For ease of describing, to set in the discharge cock of safety, one end that discharge cock 1 coordinates with firing handle 5 is outer end, and the other end is the inner, and the off-position of discharge cock 1 refers to that firing handle 5 locked the residing station of timing safety switch 1 by the outer end of discharge cock 1; The position of opening of discharge cock 1 refers to that discharge cock 1 locked the residing station of timing safety switch 1 by locking and Safety buckle 2 that discharge cock 1 is removed firing handle 5.
As depicted in figs. 1 and 2, the safety of the surgical operating instrument that this utility model embodiment provides comprise discharge cock 1, Safety buckle 2, the first elastic reset part 12 and the second elastic reset part 25, wherein:
Handle body 3, the first elastic reset parts 12 that discharge cock 1 is installed in surgical operating instrument by pivotal axis 11 are installed between discharge cock 1 and handle body 3, and provide the reset force that makes discharge cock 1 turn to off-position around its pivotal axis 11 for discharge cock 1; Discharge cock 1 locks the firing handle of surgical operating instrument 5 during in off-position under the first elastic reset part 12 effect;
Safety buckle 2 is installed in handle body 3 by pivotal axis 23, the second elastic reset part 25 is installed between Safety buckle 2 and handle body, discharge cock 1 is in the time opening, Safety buckle 2 can lock discharge cock 1 under the reset force effect of the second elastic reset part 25, in the time that carrying out firing action, firing handle 5 drive Safety buckle 2 to rotate around pivotal axis 23, the locking of arming buckle 2 to discharge cock 1.
In a kind of preferred embodiment, as shown in Figure 1, the Safety buckle 2 of safety is provided with:
During with discharge cock 1 lock fit, discharge cock 1 is locked in out to the sticking department 21 of position;
When firing handle 5 is carried out firing action, coordinate with firing handle 5 so that Safety buckle 2 around its pivotal axis 23 rotate, the drive division 22 of locking with the portion of unlocking 21 to discharge cock 1.
More preferably, in the Safety buckle 2 of above-mentioned safety, one end of Safety buckle 2 is installed in handle body by pivotal axis 23, and drive division 22 is formed at the other end of Safety buckle 2, and sticking department 21 is formed at the middle part of Safety buckle 2.Distant due between drive division 22 and pivotal axis 23, firing handle 5 drives Safety buckle 2 less to the power of drive division 22 in the time that pivotal axis 23 rotates, and is convenient to firing handle 5 and carries out firing action; Distance between sticking department 21 and pivotal axis 23 is with respect to the close together between drive division 22 and pivotal axis 23, therefore, equalising torque when discharge cock 1 locking for guarantee insurance buckle 2, latching force between sticking department 21 and discharge cock 1 is larger, has improved stability when Safety buckle 2 locks discharge cock 1.
The safety of the surgical operating instrument that this utility model provides, orientation as shown in Figure 2, when firing handle 5 does not need to carry out firing action, discharge cock 1 is in off-position, the outer end of discharge cock 1 coordinates that with firing handle 5 firing handle 5 is locked, and can prevent that firing handle 5 from carrying out firing action, orientation as shown in Figure 3, when demand motive firing handle 5 is pulled the trigger, first discharge cock 1 is rotated counterclockwise and is adjusted to out position around pivotal axis 11, and Safety buckle 2 is locked discharge cock 1 by sticking department 21 under the reseat pressure effect of the second elastic reset part 25, as shown in Figure 4, then operating firing handle 5 is rotated counterclockwise and carries out firing action to realize the firing action of surgical operating instrument around its pivotal axis 51, when firing handle 5 is carried out firing action, the drive division 22 that firing handle 5 is Safety buckle 2 provides driving force to overcome the reset force of the second elastic reset part 25 to Safety buckle 2, firing handle 5 drives Safety buckle 2 to turn clockwise around its pivotal axis 23, make to depart between the sticking department 21 of Safety buckle 2 and discharge cock 1, locking with the sticking department 21 of arming buckle 2 to discharge cock 1, thereby make discharge cock 1 under the effect of the first elastic reset part 12 reset forces around its pivotal axis 11 certain angle that turns clockwise, and in the time that firing handle 5 completes firing action reset, discharge cock 1 continues to turn clockwise around pivotal axis 11 under the effect of the first elastic reset part 12, until discharge cock 1 rotates to off-position, discharge cock 1 is locked firing handle 5 again, prevent that firing handle 5 from the accident of secondary percussion occurring, meanwhile, in firing handle 5 reseting procedures, Safety buckle 2 is rotated counterclockwise around pivotal axis 23 under the effect of the second elastic reset part 25, until Safety buckle 2 is reset to its initial position.
So the safety of above-mentioned surgical operating instrument can automatically reset, to prevent that the firing handle 5 of surgical operating instrument from the accident of secondary percussion occurring, the safety while improving surgical operating instrument operation.
